Milestone 2, circle closed

The circle | driver - bluetooth_server - bluetooth kit - application | has been closed. Quite long ago I showed how the driver was replying to some request, which is more or less what I can show in the following screenshot. But that was accessing directily to the driver sending raw data and dropping to the screen any reply from it.

What we have here is an app(bt_dev_info) that uses an API defined by the bluetooth kit (libbluetooth.so). The kit is keeping a BMessaged comunication with the bluetooth_server requesting information and waiting for a reply. The bluetooth_server is the one keeping track of all the bluetooth devices we have connected in our system and is the only one who will perfom the real hardware requests to the driver(h2generic) issuing a HCI command to the driver. The driver replies with a given HCI event to the server, the server searches who was actually waiting for the reply information, releasing the data back to the kit again, so the application gets the needed info.

All a huge background that is not bringing us new spectacular things. But its the skeleton and the base of all the Haiku bluetooth subsystem. From now on, new bluetooth functionalities are some lines of code far
(in HCI layer terms).

A BMessenged HCI layer implemented totally in userland which Linux or FreeBSD has in kernel land(almost all) Lets see how it goes with us.

Maps and legends of the unrifled. And the story that should have begun long ago starts now. Since it has been announced the completion of our final studies.

I am using Microsoft bluetooth stack and Windows Pocket PC 2003.I need to handle bluetooth connection on a very low level. I tried to use HCI layer directly calling HCI_EstablishDeviceContext method. It returns "The service has not been started" error. I need my device to report as device with some specific Code of Device. I am able to change COD using system bluetooth function, but i do not know how to accept connection on very low level.
Is it possible to use HCI layer directly ?
